Images of a South African Pastor spraying insecticide into the faces of his congregants are circulating on social media.

Lethebo Rabalago, of the Mount Zion General Assembly (MZGA), in Limpopo, has openly posted photographs on his Facebook page of him spraying congregants with Doom Super Multi Insect Killer to cure various ailments.

A post from Saturday was captioned as if quoting a congregant, saying: "I came here with a pain on my back and stomach. Now, after the prophet sprayed me with Doom I am healed. My nose was blocked since last week, but after the prophet sprayed me with Doom I feel coming out of my nose. I thank God for healing me."

When reached by phone, Rabalago declined to answer CNN's questions about his use of bug spray and hung up. MZGA could not be reached for comment, but in an interview with South African TV channel eNCA Rabalago said that God had told him to use Doom, and that he had healed countless people using it.
